I checked the manual for that HU and for the life of me can't figure out how they implement the balanced line outputs. What I've seen in other decks is that they invert the rear channels and those become the minus side of the balanced line. You get two RCA outputs for each channel and lose the rear preouts. If that's the case you should be able to make a custom cable by chopping off RCA plugs at one end and soldering them to XLR plugs or whatever your balanced line amp inputs are.
An RCA output run through a twisted pair is not a balanced line. One of the 2 wires is just a ground. Noise cancellation is only possible if the impedances of the 2 wires to ground are equal (balanced), so they pick up the same noise.
That's true even if the inputs are differential. One side of an RCA is ground. The advantage of differential inputs is that the input negative is not at ground potential, so ground loops can't exist.
Where did I say having T/P cables made your signal balanced? If your amp has so called 'differentially balanced inputs' and you use T/P cables then induced noise will cancel itself out.. I would hope the two cables would have the same impedance since they are the same size and length., otherwise they wouldn't work properly... the key is that noise enters the two wires 180 degrees out of phase (because they are twisted) and the amp amplifies the difference in potential on those two lines as opposed to amplifying just the hot line with the other as a reference with no isolation from power ground.....
Yes the advane of differential inputs is that the negative is not at ground potential because it is isolated.. And in a true balanced arrangement there is the same amount of voltage on the negative line as the positive line and the two are inverted 180 degrees out of phase in a push-pull arrangement...
No, it won't. Twisted wires don't "cancel" anything. That's a common misconception. The only thing twisted pairs do is ensure that both wires are in the same noise field. That's important for a true balanced line, but for RCA's it's meaningless. All you get is a signal line with an extra ground wire wrapped around it.
One wire is the RCA signal wire with some impedance to ground, the other is ground (zero ohms). It's physically impossible for both wires to pick up the same noise, so there's nothing for the diff amp to reject.
Wrong. Phase has nothing to do with it. A diff amp amplifies the difference between the 2 wires and rejects any ground referenced noise that's common to them. Any difference in noise becomes part of the signal. And since the ground wire in an RCA line (even if twisted) can't pick up ground referenced noise, there's no way for it to be rejected. All the noise is on one wire.
And I will reiterate that your statement is simply wrong. If you want to continue believing that nonsense, it's your choice.
Haunz is wrong.
I would like to see it.
Nope, I've done a lot of googling and checking out everything from mcintosh to crunch, but no luck. I did find that I can probably cut the ends off my rca's and the end off the goofy proprietary cable that the newer amps use and make a hybrid cable, but I will probably just use the balanced line adapter.
Yes
Not smart enough to answer that.
I wasn't really planning on it. If I did something like that I would cut the end off the rca cable after I ran it to the back where the amp is. But it doesn't seem worth it.
The balanced line adapter has inputs for all six rca's and then outputs only 3 just for a standard inputs. It ouputs and 10v also.
I was stating the configuration, not asking. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif. FYI
The only advantage is high signal and low amp gain, to minimize noise. I don't know of any amps that accept those RCA configurations either.
